Epidemiology of cancer
This document defines cancer and its major categories. It provides worldwide statistics on cancer incidence and mortality. The most common cancers by gender and region are described. Environmental and genetic factors that can cause cancer are discussed. Methods of cancer prevention, screening, and treatment are outlined. Two specific cancers - oral and stomach cancer - are summarized in terms of epidemiology, causes, diagnosis, and prevention.
L5,l6 esophageal tumors
Squamous cell carcinoma and adenocarcinoma are the two main types of esophageal cancer. Squamous cell carcinoma makes up about 90% of cases and is usually located in the upper two-thirds of the esophagus. Adenocarcinoma is more common in Western countries and usually arises from Barrett's esophagus in the lower third. Risk factors include tobacco and alcohol use for squamous cell carcinoma and obesity and gastroesophageal reflux for adenocarcinoma. Both types often present with dysphagia and have poor prognosis due to advanced stage at diagnosis.
Overview and Management of Cancer
Cancer is a degenerative disease that can be prevented and managed by following proper nutritional considerations however the prognosis highly depends on the stage of diagnosis.
cancer intro and pathogenesis
Cancer is characterized by abnormal cell growth, invasion of tissues, and spread to distant organs. The genetic material in cells can become damaged or mutated, causing abnormal cell growth and division that may form tumors. Benign tumors are non-cancerous masses, while malignant tumors are cancerous and can rapidly grow and invade nearby tissues and spread to distant sites. Carcinogenesis is the process by which normal cells are transformed into cancer cells through stages like hyperplasia, dysplasia, and neoplasia. Some major causes of cancer include environmental factors, lifestyle and dietary factors, and genetic predispositions. Common cancer types vary between developed and developing nations.

aetiology of tumour
Cancer is one of the leading causes of death worldwide. The most common cancers vary by sex and geographic location, but generally include lung, breast, prostate, and colorectal cancers. Several factors can influence cancer risk, such as age, sex, race, family history, environmental exposures, and certain precursor lesions or medical conditions. Carcinogenesis may be influenced by physical, chemical, and biological precipitating factors like radiation, chemicals, viruses, and parasites.
cancer epidemiology
This document discusses the epidemiology of cancers. It notes that cancer is the second leading cause of death in the US and fourth in India. The most common cancers vary between developed and developing countries. Cancer incidence depends on predisposing factors like familial, genetic, racial, environmental, age, and sex factors as well as chronic pre-malignant conditions and hormones. Some key points are that familial cancers are more common, smoking and alcohol increase cancer risk, and hormonal factors like estrogen can increase risks of certain cancers.

Cancer mm
Cancer is characterized by uncontrolled cell growth and the spread of abnormal cells. Cancer cells are able to grow uncontrollably and invade other tissues because of DNA damage that is not repaired. The development of most cancers can be linked to environmental exposures, like tobacco smoke, pollution, ultraviolet radiation from the sun, and certain viruses. While cancer risk increases with age as DNA damage accumulates, lifestyle factors like diet, physical activity, sun protection, and not smoking can significantly impact cancer risk and prevention. Common cancer treatments include surgery, chemotherapy, and radiation therapy, which can cause side effects by also damaging healthy cells.
Cancer Prevention
Cancer is characterized by uncontrolled growth and spread of abnormal cells. There are over 200 types of cancer. Cancer cells lose control over growth and multiplication and do not self-destruct like normal cells. Some key causes of cancer include tobacco, alcohol, diet, viruses, genetics, and environmental factors like pollution. Symptoms can include lumps, unexplained weight loss, changes in bowel or bladder function, and more. Common cancer types include lung, breast, colon, prostate, and leukemia. Diagnosis involves screening tests, biopsies, and scans. Treatments include surgery, radiation, chemotherapy, immunotherapy and more. Preventive measures include exercise, healthy diet, avoiding tobacco and excessive alcohol.

Cancer mm
Cancer is characterized by uncontrolled cell growth and the ability of cells to invade other tissues. Normal cells grow and divide in an orderly way, while cancer cells continue growing and dividing instead of dying. Cancer develops due to damaged DNA that is not repaired. Lifestyle factors like tobacco use, pollution, diet, obesity, and ultraviolet radiation exposure can damage DNA and increase cancer risk. Antioxidants from fruits and vegetables help neutralize free radicals that damage cells. Exercise, nutrition, and staying at a healthy weight can help prevent cancer development. Cancer treatments include chemotherapy, radiation, and surgery, but prevention through lifestyle is most effective.

Intestinal fistula (Naqvi Syed Noor group 11) copy.pptx
Intestinal fistulas are abnormal connections between two epithelial surfaces, usually involving the gut and another organ. They can form due to abdominal surgery (75-85% of GI fistulas), inflammation, infection, trauma, or radiation. Symptoms depend on the location of the fistula but may include diarrhea, weight loss, abdominal pain, pneumaturia, or fecal discharge from surgical incisions. Fistulas are classified based on their anatomical location and cause significant morbidity, mortality, and healthcare costs.
scabies-160908065024.pdf Dermatology Dieasease
Scabies is caused by tiny burrowing mites that infest the skin and lay eggs, causing intense itching. It spreads through direct, prolonged skin-to-skin contact. The mites burrow beneath the skin and lay eggs, triggering an allergic reaction and itching. Symptoms include itching and thin burrow tracks on the skin. Doctors diagnose scabies by examining the skin for mites or eggs under a microscope. Treatment involves applying prescription creams or lotions to kill the mites. Close contacts may also need treatment to prevent reinfestation.

Layser therapy
Laser therapy uses light amplification to generate coherent beams of monochromatic light. It has been used in physiotherapy since the 1960s when its effects on wound healing were first reported. Low-level lasers are classified by the FDA and produce effects through photobiomodulation rather than heat. The physiological effects of laser therapy include reducing pain and inflammation, promoting tissue healing, and accelerating nerve regeneration.
Layser therapy
Laser therapy uses light amplification to stimulate tissues. It has a long history dating back to Einstein describing the theory that was transformed into laser therapy. Low-level lasers are classified based on power and safety, with classes 1-3 being most commonly used in physical therapy. Lasers have physiological effects like reducing pain and inflammation while promoting tissue healing. Common indications are musculoskeletal pain, wounds, and neurogenic pain. Treatment involves calculating the appropriate laser dose and applying it using contact or non-contact techniques.
TENS by AK
Transcutaneous electric nerve stimulation (TENS) is a non-invasive method of pain relief using electric stimulation of sensory nerves. There are different types of TENS including conventional/high frequency TENS, acupuncture/low frequency TENS, burst TENS, and brief/intense TENS, each with different parameters and mechanisms of pain relief. TENS is commonly used to relieve acute pain after surgery or childbirth as well as chronic pain from conditions like low back pain, arthritis, and myofascial pain by applying electrical stimulation to sites over painful areas, dermatomes, or acupuncture points. Contraindications for TENS use include pacemakers, untreated pain conditions, and certain cardiac or neurological conditions.
